一、錯誤與原因
在Windows上沒有用於Python 3.7的輪子（預構建包）（有一個用於Python 2.7和3.4到3.6），因此需要在PC上準備構建環境以使用此包。因爲有些軟件包很難在Windows上構建，所以找到3.7的輪子更容易一些。
這是安裝時報的錯：
> pip3 install pyaudio

二、解決方法
我也是搜索了一下，參照stackoverflow這個回答：
- 打開
python終端，在一個.py文件右鍵，選擇Edit with IDLE->Edit with IDLE3.7(32 bit)打開，然後使用F5快速啓動，即可看到你的python所有基本信息，比如我的版本是3.7.4，32位的
Python 3.7.4 (tags/v3.7.4:e09359112e, Jul 8 2019, 19:29:22) [MSC v.1916 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license()" for more information.
- 下載你所需的輪子，根據你的信息下載相匹配的輪子，比如如果是
64 bit (AMD64)，就要下載PyAudio‑0.2.11‑cp37‑cp37m‑win_amd64.whl，而我需要下載的是上一個PyAudio‑0.2.11‑cp37‑cp37m‑win32.whl，以下圈出的是與64 bit(AMD64)適用的
![在這裏插入圖片描述]()
- 找到相對應的輪子下載後，在輪子所在文件夾內安裝
pip3 install PyAudio-0.2.11-cp37-cp37m-win32.whl
# 出現以下信息代表安裝成功
D:\User\Downloads>pip3 install PyAudio-0.2.11-cp37-cp37m-win32.whl
